Abstract (en)
A watch component includes a base material including a first region having a surface at which a plurality of recessed portions are formed and a second region having a smooth surface, and a multilayer film configured to cover at least a portion of the base material. When viewed in a cross-sectional view taken along a thickness direction of the base material, the plurality of recessed portions are defined by a first side and a second side that is tilted with respect to the first side and is in contact with the first side at an end portion, and a hue angle of the first region is greater than a hue angle of the second region.
